By the construction of the frame, the section 6 containing the motor,driving and turning wheel, and connections can be attached to framesections 1 carrying differ- .ent implements. Y

The frame element 2 is provided with a wheel as a caster wheel '9 at itsouter end.

The implement supported by the frame includes a movable member which isactuated by the motor, and the implement here shown is a mower includinga finger bar 10 and a reciprocating knife 11-, the mower being arrangedin front of the frame element 2 and caster wheel and atone: side of thebeam 1 and the path of thewheels 5. and 7.-

The mower is provided with inner and outer swath boards 10 and 10 whichdeflect 1 the grassor grain inwardly so that it will not be run over bythe caster wheel 9-01- the driving an turning wheel 7.

v The steering wheel 1s arranged to travel. in advance of the finger barand entirely at one side of the standing grass or grain, and

in the path cleared by the outer swath board during the previous trip ofthe machine across the field as illustrated in dotted lines, Fig.1, andthe driving and turning wheel 7 is also arranged to travel in said pathcleared by. the outer swath board .during the previous trip of themachine. Hence-the steering wheel and the driving and turning wheeltravel in the same path.

The steering'wheel 5 is operated'b a rotatable shaft 12 suitablysupported ythe frame 1 andhavinga worm 13 at one end meshingwitha wormgear 14 on the upright spindle 15: ofthe forks 4, the shaft 12 hav-. mga handwheel 16 at its other end located" within reachof the seat 17which is sup- ;ported on the frame section 6.

The;shoe 21 is supported ,by a suitable swinging frame and the parts 29 and30 swing during theraising of the finger bar about an axis located nearthe axis of the shaft 2.

The rear end of the swinging frame 30 is adjustable vertically to tiltor direct the edge of the finger bar and knife upwardly or downwardlymore or less into different angular relations relatively to the ground,and this adjustment is effected by a lever 30 mounted on the frame 1within reach of the seat and having an arm 30",-Fig. 5, which isconnected by a link 30 to the slotted bearing Q30 at the rear'end of theswinging frame 30. The slotted bearing 30 receives a box 30 mounted onthe pivot 30 on which the The lever 30* is held in its adjusted positionby a pawl operated by a grip lever on the lever 30 and cooperating witha rack on the beam 1.

The levers 18 and 19 may be connected together in any suitable manner,one way of efiectin this result being shown in Fig. 9,

the lever" 19 is shown with a laterally'extending lug 31 extending inthe rear -;of; t he lever 18, the lever '19 being movable laterallyagainst the influence of its own resiliency to disengage the lug 31 fromthe lever- 18.- Suitable lifting springs 32 and33 are connected to theframe and, respectively, to the. levers 18 and 19.'

351 is an axle upon which the driving and corner-turningwheel 7 ismounted, this axle beingconne'cted to the frame by an upright pivotalconnection as the upright bearing 35 at the'inner end of the axle, and aspindle or shaft 36 extending throu h the bearings 37 on'theyp'ortion 6of the rame and through thebearing-35, see Figs. 4,5 and 8. w

The wheel 7 is movable about its upright axis" from its normal positioninto and out ofan angular position relatively to the normal line oftravel of the machine, as indicatedin' dotted lines, Figs. 1, 4 and 5.

' The power-transmitting connections between the motor 8 andthe drivingand turnin wheel 7 comprises a ear 39 arranged concentric with the axisof the wheel 7 and fixedthereto, a gear 10 mounted on the spindle 36'.and having a gear ring 41 meshmg'with the gear 39, and a gear ring 42meshing with-a gear 43 mounted-on one end of afshaft Mjournaled in abearing 45 in the frame section 6 and extending lengthwise of theframe,'a gear 46, mounted on the front end of said shaft 4% and meshingwith a In the normaljoperation. of the, machine,; the motion istransmitted from the motor shaft 52 to the shaft 51, gear-', gears 48,47, beveled gear 46", shaft 4, gears 46, 43, "40 and 39. i
